UK George V Half Crown correction

https://en.numista.com/catalogue/pieces3156.html
This coin entry is quite badly wrong - The KM should be 818.1 not 818 (there is no such coin), the metal should be 0.925 Silver and it was only struck between 1911 and 1919. I have already corrected the mintages, but I will need someone from the team to remove the redundant years and carry out the other corrections. The picture is also wrong - it is of a 1921 KM818.1a, but my scanner is playing up at the moment. As soon as I get it sorted I can upload scans of my 1916.

Many thanks, Rick

Sorry, the diameter also needs correcting - should be 32.3mm.

Many thanks

will do
